SOMERSWORTH — Officials in Massachusetts have closed another compounding center in the state as part of a crackdown in relation to a widespread outbreak of fungal meningitis.

Infusion Resource, a pharmacy located in Waltham, Mass., was closed after a surprise inspection revealed unsanitary conditions in an area of the company where sterile injectable medications are prepared. The pharmacy was also administering injections — something it wasn’t licensed to do.

Despite the closure, none of the products handled at Infusion Resource have been linked to the current outbreak of meningitis.

In New Hampshire, 11 cases of fungal meningitis have been confirmed. Three PainCare locations — in Somersworth, Merrimack, and Newington — have previously been linked to an injectable steroid that spurred the outbreak. These clinics quickly pulled the product from shelves and informed patients upon learning of possible health risks.

The New England Compounding Center, a Framingham, Mass., specialty pharmacy, is accused of shipping the tainted medication to 23 states. The pharmacy has since closed operations and recalled all products it produced since January 2012.

Although the current outbreak is linked to Methylprednisolone Acetate — an injectable steroid used primarily to treat back pain, the Food and Drug Administration has asked all healthcare providers to contact any patients who were treated with any medication from the pharmacy after May 21.

Locally, Wentworth-Douglass Hospital, Portsmouth Regional Hospital, and Exeter Hospital were listed by the FDA as facilities that received shipments of other products from the Framingham pharmacy. These hospitals have since contacted patients out of an abundance of caution and no new cases have been reported.

Nationally, 354 cases of fungal meningitis across 19 states have been confirmed, with 25 deaths resulting.
